Lifter-Earth class robot) is a curious, blue-collar working trash compactor

robot tasked with cleaning up mountains of consumer garbage from the

Earth’s surface. WALL-E is completely alone in this mess because

human beings have moved off the world on a permanent vacation,

due to pollution and the inability of the planet to support life.

TWALL-E collects artifacts and treasures from the glut
of consumer by-products, which help him in his search
o keep this endless, mundane chore interesting,

for the meaning of life and his own worth. WALL-E
manages to squeeze in a little fun, too, in the brief, shallow
respites he takes from his manual labors.

On the toy shelves at Disney, WALL-E is another ‘Stor-E’

Sensors, Sounds, and Responses

Ten deluxe grade brushed motors manipulate WALL-E’s
movements based on input from several multi-directional
smart sensors. Here’s what WALL-E can do, and how he
does it!

FollowMode

When WALL-E detects any movement, he will turn
around and follow it. When WALL-E detects movement
behind him, he will turn around to examine the source of
the movement, according to the owner’s manual. These
features are available when the unit is in FollowMode.

WALL-E has a square FollowMode button on top of his
front container area, signified by a red circle. Users can also
activate FollowMode via remote through an oval button
with a picture of WALL-E following sound waves.

WALL-E will use his three forward microphones to
detect and follow you. Simply clap twice and he will follow.
Continue clapping twice as you move and WALL-E will
continue to follow the sound of your hands.

Using his infrared obstacle detection and avoidance
sensors, WALL-E can detect obstacles in his path, stop
movement, and change course to avoid them so as not to
hang itself up on the landscape.

There are four infrared sensors: three in the front and
one in the back. WALL-E emits an infrared light, and an
infrared receiver processes the reply when the light bounces
